Engenharia de interações e de reservatórios
(Universidade Federal de São Carlos, 2008-05-17)
In this work we first present a protocol to build effective interactions between two cavity modes, considering a two-level atom under the action of classical fields. Bilinear Hamiltonians associated with parametric up- and ...
Peso de Drude em anéis unidimensionais com potenciais de substituição e atravessados por fluxo magnético
(Universidade Federal de São Carlos, 2002-04-11)
In the present work the Drude weight is calculated to study the capacity of conduction at finite temperatures in one-dimensional rings with the potencial given by the sequences of different degrees of randomness and threaded ...
